Using a hypothesis-driven and integrative framework, Sociobiology of Caviomorph Rodents establishes parallels and differences between caviomorph rodents and other animal models to provide a comprehensive understanding of caviomorph rodent social systems. Including epigenetic, neuroendocrine and developmental mechanisms of social behavior, it identifies the fitness costs and benefits of social living in present-day caviomorph rodent populations as well as quantified evolutionary patterns or trends. The book includes:
Distribution and ecological diversification of caviomorph rodents
Diversity of social behavior in caviomorph rodents
Comparative neurobiology and genetics of mammalian social behavior
Mechanisms of social communication
Causes and evolution of group-living
Cooperation in caviomorphs
Fitness consequences of social systems
This book will appeal to researchers and students of biology interest in behavioral endocrinology and neurobiology, behavioral ecology and evolutionary biology. It will also appeal to social scientists and psychologists interested in the interdisciplinary approach to social behavior.

Fully integrative approach to the socibiology of caviomorph rodents
- Brings together research on social systems with that on epigenetic, neurendocrine and developmental mechanisms of social behavior
- Describes the social systems of many previously understudied caviomorph species, identifying the fitness costs and benefits of social living in current day populations as well as quantified evolutionary patterns or trends
- Highlights potential parallels and differences with other animal models

Luis A. Ebensperger, P. Universidad Católica de Chile, Chile Luis Ebensperger has developed a research career to examine causes (ecological, evolutionary) and consequences of rodent social living. He has successfullycombined field observational, demographical, and lab approaches to address why animals congregate, how they cooperate, and what are the fitness effectsof group-living and cooperation. His recent work has addressed the neuroendocrine and immune responses of social mammals and the links between these mechanisms and direct fitness. He has been able to acquire evidence not only from several caviomorph rodent models, but also from other animal models, including ungulates. In addition to publishing research papers in high impact journals, he has produced papers aimed to summarize andprovide an integrative view to current social behavior theory. Loren D. Hayes, Department of Biological and Environmental Sciences, University of Tennessee at Chattanooga, USA Loren Hayes' research program examines the ecological and neural drivers of social systems, costs and benefits of communal care, and fitness consequences of group-living. Hayes has successfully combined field and laboratory work to determine the mechanisms of maternal investment and neuroendocrine sources of direct fitness variation in social voles and degus, respectively. His NSF-funded program includes collaborations in Chile, the U.S., and Taiwan and has generated 30 peer-reviewed papers, including two synthetic reviews on an integrated theory for sociality. Additionally, he co-organized a workshop on vertebrate sociality in Chile, participated in a National Evolutionary Synthesis Center working group on integrative animal sociality, and co-coordinated a Journal of Mammalogy Special Feature on caviomorph social systems.
